Synopsys Test Automation Engineer interview questions

Applied online for the role. Got an email response from the HR recruiter and we scheduled a phone conversation at a specific date and time. However I got stood up by the recruiter who later clarified that there was an emergency. The recruiter called the next morning without a heads up to discuss the role. Gave me an online test to complete. Once I completed the test, the recruiter scheduled a phone screen with the hiring manager. The phone screen only had some general questions and a few technical and behavioral questions. The manager indicated to me that I would be called for an onsite interview the following week. But the week came and went without any response. I reached out a few times to the HR recruiter but got no response about my status. This is was a real waste of time and I had a disappointing experience.
